Safe Drinking Water Act

test

On April 10, 2024, U.S. EPA announced a National Primary Drinking Water Regulation (NPDWR) establishing legally enforceable Maximum Contaminant Levels (MCLs) and non-enforceable Maximum Contaminant Level Goals (MCLGs) for six per- and polyfluoroalkyl substances (PFAS) in drinking water under the Safe Drinking Water Act (SDWA).

The final rule requires public water systems to: (1) complete initial monitoring for these PFAS by 2027 and provide public notice of initial monitoring results beginning in 2027; (2) implement solutions by 2029 to reduce these PFAS if drinking water levels exceed the MCLs; and (3) starting in 2029, take action to reduce PFAS in response to violations of the MCLs and to provide public notice of any such violations.

On April 10, 2024, the U.S. EPA released its federally enforceable drinking water limits for certain toxic PFAS “forever chemicals” under the federal Safe Drinking Water Act. The final rule will “reduce PFAS exposure for approximately 100 million people, prevent thousands of deaths, and reduce tens of thousands of serious illnesses.”
